Morphology

department + of + Defense

The phrase is compositionally built from 'department' (an organizational unit) + 'of' (linking) + 'defense' (military protection), so its meaning as an agency responsible for national/military defense is directly inferable from the constituents. The 'Department of X' construction is cross-linguistically common, so a B1 learner who knows the words would understand this refers to a government department overseeing defense, even if they might not know the specific U.S. institutional nuances.

Etymology

Department of Defense got its name after the U.S. joined separate military offices into one group; the word defense was chosen to show the job is to 'protect' the country rather than to 'attack'. That's why today the name tells you it is the government office in charge of national security and the armed forces.
